colorize
✓ should return ' <value>' for a scalar value
✓ should return '-<old value>', '+<new value>' for a scalar diff
✓ should return '-<removed key>: <removed value>' for an object diff with a removed key
✓ should return '+<added key>: <added value>' for an object diff with an added key
✓ should return '+<added key>: <added stringified value>' for an object diff with an added key and a non-scalar value
✓ should return ' <modified key>: <colorized diff>' for an object diff with a modified key
✓ should return '+<inserted item>' for an array diff
✓ should return '-<deleted item>' for an array diff
diff
with simple scalar values
✓ should return undefined for two identical numbers
✓ should return undefined for two identical strings
✓ should return { __old: <old value>, __new: <new value> } object for two different numbers
with objects
✓ should return undefined for two objects with identical contents
✓ should return undefined for two object hierarchies with identical contents
✓ should return { <key>__deleted: <old value> } when the second object is missing a key
✓ should return { <key>__added: <new value> } when the first object is missing a key
✓ should return { <key>: { __old: <old value>, __new: <new value> } } for two objects with diffent scalar values for a key
✓ should return { <key>: <diff> } with a recursive diff for two objects with diffent values for a key
with arrays of scalars
✓ should return undefined for two arrays with identical contents
✓ should return [..., ['-', <removed item>], ...] for two arrays when the second array is missing a value
✓ should return [..., ['+', <added item>], ...] for two arrays when the second one has an extra value
✓ should return [..., ['+', <added item>]] for two arrays when the second one has an extra value at the end (edge case test)
with arrays of objects
✓ should return undefined for two arrays with identical contents
✓ should return [..., ['-', <removed item>], ...] for two arrays when the second array is missing a value
✓ should return [..., ['+', <added item>], ...] for two arrays when the second array has an extra value
✓ should return [..., ['~', <diff>], ...] for two arrays when an item has been modified (note: involves a crazy heuristic)
